How to Validate Your Business Idea Without Writing a Single Line of Code

Hey there! I'm Philipp, and I've learned a thing or two about validating business ideas the hard way. After building PostFlow (my AI-powered content creation tool) and helping countless enterprises launch new ventures through Reruption, I'm here to share the fastest way to test if people will actually pay for your solution.

The Problem with MVPs

Look, everyone talks about building MVPs (Minimal Viable Products), but here's the thing - even MVPs are often overkill. I'm guilty of this myself. With PostFlow, I kept tinkering and building because, let's face it, building stuff is fun as hell. But that's exactly how you end up with a solution nobody wants.

The Mom Test - Your New Best Friend

There's this kickass book called "The Mom Test" - it's basically my bible for customer research. You can blast through it in an afternoon, and it'll completely change how you think about validation. The core idea? Don't let your love for your own idea blind you from reality.

How to Actually Test Your Idea

1. Sell the Service Before the Product

Here's what most people don't tell you: You can often sell a solution without building anything. Let me give you a real example.

When I started PostFlow, instead of diving straight into development, I:

Reached out to potential customers
Offered video content creation as a manual service
Got paid before writing a single line of code
Did everything by hand using tools like CapCut and Opus

Was it scalable? Hell no. My hourly rate was probably embarrassing. But guess what? I learned exactly what the product needed to be.

2. Find Your Test Audience

Different products need different approaches:

B2B software? Hit up LinkedIn
Jewelry line? Instagram is your jam
Health food product? TikTok might be your scene

3. Cold Outreach That Actually Works

Here's my LinkedIn strategy (that doesn't suck):

Use LinkedIn search to find your target audience
Send honest messages asking for feedback (not sales pitches)
Be genuine about wanting their input

Pro tip: People actually love helping if you're not trying to sell them something!

Why This Method Works

By manually delivering your service first, you:

Validate real market demand
Get paid to learn about your customers
Understand what to automate
Avoid building something nobody wants

A Real Talk Moment

Look, you're probably not building the next SAP or some fancy-ass flying taxi (if you are, we should talk - my consulting firm Reruption loves that kind of crazy). You're likely building something more niche, which is perfect for this approach.

Speaking of which, this is exactly how I validated PostFlow - by manually helping content creators with their ideation and scheduling problems before building the automation. Now it's a tool that analyzes video snippets and auto-generates content pieces across platforms. (First 30 scheduled pieces are free, btw - just saying! 😉)

The Bottom Line

Stop overthinking it. Start selling your solution as a service. Yeah, it might mean doing things that don't scale at first. But that's exactly how you figure out what to build.

Trust me on this one - I've been through this rodeo multiple times, both with my own ventures and helping others through Reruption. When I'm not sailing around Mallorca or mountain biking in Stuttgart, I'm usually sharing these kinds of insights on the #buildinpublic podcast with my buddy Paul.

Remember: The goal isn't to build something perfect - it's to solve a real problem that people will pay for. Now get out there and start testing!
